Analysts look to rejectthe null hypothesis because doing so is a strong conclusion. This requires evidence in the form of an observed difference that is too large to be explained solely by chance. Failing to reject the null hypothesis—that the results are explainable by chance alone—is a wea...

What is an alternative hypothesis? What is a theory in science? What variables must be included in a testable hypothesis? What does hypothesis mean? What variable is predicted by the hypothesis? What is all scientific knowledge based upon?
Science involves the gathering of empirical data, followed by analysis leading to the formation of general principles and ultimately an explanatory theory. New hypotheses may be suggested or derived from the theory, leading to further gathering of data in a cyclical fashion....
When doing a science experiment, after forming a hypothesis, what should you do next? A. Start experimenting immediately. B. Collect relevant materials. C. Record observations. D. Design the E. xperiment. 相关知识点: 试题来源: 解析 D。形成假设后,应该设计实验。直接开始实验、收集相关材料和...
A hypothesis is an educated guess or prediction of what will happen. In science, a hypothesis proposes a relationship between factors called variables. A good hypothesis relates an independent variable and a dependent variable. The effect on the dependent variable depends on or is determined by wha...

Within social science, a hypothesis can take two forms. It can predict that there is no relationship between two variables, in which case it is anull hypothesis. Or, it can predict the existence of a relationship between variables, which is known as an alternative hypothesis. ...
, but none can ever be proved to be true. One aspect of a proper understanding of the word "hypothesis," as used in science, is that only a vanishingly small percentage of hypotheses could ever potentially become a theory. (general) An assumption taken to be true for the purpose of ...
